Claims.
This inventionV relates to a machine for picking cotton.
One of the objects of the invention is to provide a machine having picking rolls arranged 5 in opposed groups, the rolls of these groups being revolvable about a common center during the operation of the machine.
Another object is to provide picking rolls dis posed in groups, the rolls being independently revolvable about individual axes so as to be brought successively into positions for engaging the cotton and delivering it. i
A still further object is to provide picking rolls which, during their rotation about their individual and common axes will be swung laterally toward and away from the plants being acted on so that bolls located at any points on the plants will be reached ultimately by one of the rolls and removed.
With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.
In the accompanying drawings the preferred form of the invention has been shown.

Figure 14 is a similar view of another dofling plate. Y o
Referring to the gures by characters of reference, l designates supporting wheels carrying 65. yokes 2 on which is arranged any suitable superstructure 3. This super-structurev can be used to support a motor 4 designed to drive the mechanisin of the picker. The machine can-.be -propelled alongvlo'ng rows 'of plants underv its own 70 power or `can be pulled by any suitablemeans provided for that purpose. y f
Suitably suspended from theV side portions of the super-structure are picker frames 5.:
Each of the picker frames is provided adjacent to its rear end with an upwardly extendedhousing 6 which is provided with superposed inlet openings 7 and extending from each picker'frarne at each of the openings 7 is a guide housing Vformed of lupper and lowerplates 8 and 9vjoined 80 by connecting walls 10. vThe number of these housings is the same as the number of picking units carried byv each frame 5. In the present instance four picking units are carried by each frame as will be explained hereinafter, and, consequently, four of the guide housings are extended from each frame. The guide housings on each frame are`disposed directlyl opposite the corresponding housings of the otherv frames and are 'extended toward each other.
' Mounted'on each of the picker frames 5 are superposed brackets 11 located-between the housings and the front ends of the frames.' To each of 'these brackets is hingedly connected the front end portion ofV an oscillating frame 12. This frame extendsu past the plates 8 and 9 `of the housing associated therewithand is provided, at its rear end with a bracket 13. `A combined bracket and deflecting arm 14 is secured to the forward portion of frame 12 and curves laterally and rearwardly, its` back end being supported by a bracket 15 which extends fromthe frame 12. A casing 16 is secured to the rear' endof the arm 14 and another casing 17 is secured to the bracket 13. Each of these casings is'provided with a 105 head 18 which is fitted within and secured to ,the casing. l
A shaft 19 is journaled in the brackets 13 and 15 and is concentric with the casings 16 and 17. Each casing. can be adjusted annularly on shaft no 19 after which it can be held against rotation by any suitable means, such as a set screw 2G carried by the adjacent bracket.
The head 18 of casing 17 has a cam 21 xed thereto. This cam has a portion of its periphery cut away as shown at 22 and constitutes a track for the purpose hereinafter explained. If the casing 16 is adjustable annularly its head 18 is also provided with a cam 21 such as shown, for example, in Figures 6 and 7.
Secured to the shaft 19 so as to rotate therewith within the respective housings 16 and 17 are disks 22 and in these disks are journaled rock shafts 23 which are regularly spaced annularly. To one end of the shaft is secured a cap 24 having a tangential finger 25 so positioned as to travel along the periphery of the` cam 21. Secured to each shaft 23 and extending longitudinally thereof is an arcuate strip 26 which embraces the.
shaft and extends close to the disks 22. One edge of the'Y strip' 26 is formed with teeth 27 the points of which are spaced from the shaft.
.Each shaft 19 has a sprocket 28 located back of the arm 14 and adapted to receive motion through a chain 29 from anothery sprocket 30 secured to a shaft 31. This shaft is journaled in brackets 32 projecting outwardly from the frame 12. The shaft is joined by a universal coupling 33 to a shaft 34 journaled in a suitable bearing 35 provided therefor on the frame: 5. All of the shafts 34 carried by the frame 5 are adapted-to be driven simultaneously and at the same speed by chain and sprocket mechanism, indicated generally at -36, which, in turn, is driven by a power shaft 37 i having a driving connection 38 with the motor 4.
Each picking unit projects into one end of a box 39 which is open.` The other end of this box is slidably `mounted in the adjacent housing formed bythe plates 8 and v9 and the connecting walls 10. The-bottom of the box is preferably inclined so that material falling thereon will slide into the housing by gravity. The front and back walls of the box as well as the corresponding walls of the box as well as the corresponding walls of the housing can be curved and concentric with the hinge 40 whereby frame 12 is connected to bracket 11.
A pitman 41 connects bracket 13 to one of a series of cranks 42 carriedbyfshaft 43 which is journaled on the rear Yportion of the frame 5. This shaft is adapted to receive motion from any suitable mechanism rprovided for that purpose. For example, the upper end of the shaft can be provided with a worm gear 44 engaged by a worm 45 carried by a shaft 46 which extends transversely through the upper portion of the housing 6. On this shaft has been mounted an endless elevator 47 disposed vertically` within the housing 6 and extending backof the openings 7 belonging to all of the picking units. This elevator has outwardly extending blades 48 and that portion of the elevator nearest theopening moves upwardly Y Y Y y j As has already been explained theV two picker frames 5 are oppositely disposed and each of these frames carries several picking units. In the present instance each frame has ve picking units and each unit is of the same construction and `operates in the same manner as the other units. The picking units are supported between thel frames 5 and the cranks42 are so positioned lthat the corresponding ones on the two shafts 43 operate in unison. In otherwords when one crank 42 is extended to the right the corresponding crank on the other shaft is also extended to the right,
Thus the mechanisms controlled by the two cranks will simultaneously move in the same direction laterally.
When the machine is moved forwardly a row of plants to be acted on will be located between the two opposed picking units. All of the picking units will rotate continuously as indicated by the arrows in Figure 3, motion being transmitted to them from the motor 4 through thepower shaft 37 and their connections which have already been described.
As each picking unit rotates with its shaft 19 those rock shafts 23 nearest to the plants will be held against rotation about their individual axes because the fingers 25 connected thereto are rid- The advancing finger will be swung back into the recess 22' so that it can pass under pin 49, as shown by broken lines in Figure 7. Movement of the finger will cause shaft 23 to rock and withdraw fingers 25 from engagement with the cotton.
The cotton will then be deposited on the bottom q of the `box 39 and travel downwardly into the housing back of the box. After the fingers have passed downwardly below the bottom of the box 39 they will come against theadjacent end of the recess 22 and rock the shaft 23 back to its normal j position where the teeth 27 can again vengage the cotton.
It will be apparent fromr the foregoing that during each rotation of the picking unit the several shafts 23 included therein will be brought into active position successively to cause their teeth 27 to strip cotton from the plants and to convey the cotton back to and deliver it into the box 39.
TheV cotton entering the housing formed by the plates 8 and 9 and the walls 10 will pass through the openings 7 and be picked up by the blades of the conveyor or elevator 47.
While the cotton is picked from the plants by the unit as already explained, said unit can be oscillated transversely by the pitmans 41 so that each of the picking units will thus be forced laterally into the plants and then withdrawn therefrom. This will insure picking of practically all of the cotton on theplants, because 353 the picking units are thus caused to comb through the plants intermittently. The arms 14 guide the plants properly into the space between lthe picking unitswhile the rear end port-ions of with an inclined dofling or stripping plate 50 H5 The roll 54 used in this modified structure extends across the space between the free edges of plates 50 and 52 and is supported close to the teeth 51 and 53 by a shaft 55 the ends of which are journaled in plates 56 xedly connected to and extending laterally from frame 12. To the periphery of the roll is fastened a picking strip 57 which extends throughout the length of the roll and a short distance around the roll. Along each longitudinal edge of the strip are provided picking teeth 58 which are spaced from the surface of the roll as shown and are adapted to travel close to but out of contact with the doffing teeth 51 and 53.
Secured to the shaft so as to rotate therewith, is a gear 59 constantly meshing with a rack 60 which bears downwardly on the gear and is pivotally connected at one end to a disc 6l carried by shaft 31.
One unit such as described is adapted to be used in lieu of each of the picking units heretofore described. It will be apparent that when the machine is moved along a row of cotton plants the rotating shaft 3l will cause the rack 60 to reciprocate under a guide pin 62 and rotate gear 59 back and forth. This will produce a corresponding back and forth rotation of roll 54. Consequently as disc 61 travels from the position shown in Figure 9 and in the direction of the arrow to the position shown in Figure 10, the upper series of teeth 58 will travel toward and downwardly through the plants adjacent thereto stripping from them the cotton fibers and carrying the cotton laterally and then upwardly past the teeth 51 until the roll reaches the position shown in Figure l0. Continued rotation of disc 61 in the direction of the arrow in Figure 10 will result in reversal of the rotation of roll 54 with the result that the cotton which had been brought to the space between the plates 59 and 52 will be carried downwardly to the teeth 51 and stripped thereby from the teeth 58. As this operation is taking place the roll teeth 58 in Figure 10 will comb upwardly through the adjacent plants and remove cotton therefrom carry it upwardly and laterally and thence downwardly past the teeth 53 until brought to the position of the lower teeth 58 in Figure 9.
Further rotation of disc 61 will again reverse the movement of the roll 54 with the result that the cotton which has been brought to position under plate 52 will be stripped off of teeth 58 by the teeth 53 as the roll 54 proceeds in the direction indicated by the arrow in Figure 9.
In practice it has been found desirable to extend the toothed strip 57 over approximately one-fourth of the circumference of the roll 54 so that should any cotton pods or other long growths become caught by one set of teeth 58 it would not be possible for it to become caught in the other set of teeth and thus choke the mechanism.
The cooperation of teeth 58 with the teeth 51 f and 58 is such as to not only assure positive stripping of the cotton from the roll 54 even though it should be mixed with long grass or vegetation, but it also insures proper feeding of the harvested cotton back into the box 39 and housing 9 so that it can be carried off by the means provided therefor.
By utilizing a picking roll `for a back and forth rotation it will pick cotton on both the up and down movements, thereby insuring a larger percentage of picked cotton during one harvesting operation than it would be possible to obtain by other mechanisms.
T he teeth 58 can be sharpened readily by detaching plate 57 from the roll 54. It is also possible to detach the plates 50 and 51 should it be found desirable to sharpen the teeth thereon.
